Abstract
A rotational cutting blade assembly for use with a garden tool. The rotational cutting blade assembly including a frame defining an axis of rotation and including a blade mounting point, where the blade mounting point includes a cutting boundary, and where the cutting boundary is subdivided into at least one access slot and at least one guard. The rotational cutting blade assembly also including a cutting element configured to be attached to the frame at the blade mounting point, where the cutting element includes at least one cutting edge, and where the at least one cutting edge is immediately adjacent the cutting boundary of the blade mounting point when the cutting element is attached thereto.
Claims17
A rotational cutting blade assembly for use with a garden tool, the rotational cutting blade assembly comprising:
- a frame defining an axis of rotation, the frame including a blade mounting point, wherein the blade mounting point includes a cutting boundary, and wherein the cutting boundary is subdivided into at least one access slot and at least one guard;
- and
- a cutting element configured to be attached to the frame at the blade mounting point, wherein the cutting element includes at least one cutting edge, and wherein the at least one cutting edge is immediately adjacent the cutting boundary of the blade mounting point when the cutting element is attached thereto;
- wherein the blade mounting point includes a pocket formed into the frame, wherein the cutting element is sized and shaped to be at least partially positioned within the pocket, and wherein the pocket extends into the frame in a direction parallel to the axis of rotation such that the cutting element may be inserted into and removed from the pocked in a direction parallel to the axis of rotation.
A rotational cutting blade configured to rotate about an axis of rotation, the rotational cutting blade comprising:
- a hub defining the axis of rotation,
- a first arm extending radially from the hub to define a first distal end, wherein the first arm includes a first blade mounting point configured to at least partially receive a cutting element therein, wherein the first blade mounting point includes a first cutting boundary, and wherein the first cutting boundary is subdivided into at least one access slot and at least one guard;
- a second arm extending radially from the hub to define a second distal end, wherein the second arm includes a second blade mounting point configured to at least partially receive a cutting element, therein, wherein the second blade mounting point includes a second cutting boundary, and wherein the second cutting boundary includes at least one access slot and at least one guard;
- and
- wherein the at least one guard of the first blade mounting point is positioned over a first range of radial distances from the axis of rotation, wherein the at least one access slot of the second blade mounting point is positioned over a second range of radial distances from the axis of rotation, and wherein the first range of radial distances at least partially overlaps the second range of radial distances.
